Jaferabad Aloes Is made at Jaferabad, a town on the coast of 

 Kathiawar, belonging to the Ilubshis of Jinjira, a family of 

 African origin. The drug in mass is black ; it has a glassy 

 fracture ; thin pieces are yellowish-brown and translucent ; the 

 powder is of a dull yellow ; the odour powerfully aloetic, with 

 an aroma like Socotrine aloes ; when brought in contact with 

 nitric acid it does not turn red- Its reaction is then the same 

 as Socaloin- Jaferabad Aloes is generally in the form of flat 

 circular cakes. From Zanzibar an aloe is imported which very 

 closely resembles Jaferabad; it gives the same reaction with 

 nitric acid. 



Yamani or Moka Aloes, also called Aden Aloes, is 

 imported from Arabia, and is the kind most in use among the 

 natives of India. It varies much in quality. It is of a black 

 colour in mass, and somewhat porous, but thin fragments are 

 translucent and yellowish-brown j the odour is powerfully 

 aloetic, without the aroma of Socotrine or Jaferabad Aloes ; 

 medicinally it appears to be sufficiently active. With nitric 

 acid it gives a deep red colour, like Barbadocs ; the solution in 

 sxili)huric acid is not affected by nitric acid fumes. 



Mysore aloes is made in Mysore from a plant which is pro- 

 bably only a variety of A. vera. It is called Musambra in 

 Southern India, and is used in the arts in preparing a false 



jnldinj? for decorations. 



Chemical comjyosltion. — All kinds of aloes have an odour of 

 the same character and a bitter disagreeable taste. The odour, 

 which is often not unpleasant, especially in Socotrine Aloes, is 

 due to a volatile oil, which the drug contains only in minute 

 proportion. The oil is a mobile pale yellow liquid, of sp. gr. 



0-8G3, with a boiling point of 266^ to 271^0. 



" Pure aloes dissolves easily in spirit of wine with the excep- 

 tion of a few flocculi ; it is insoluble in chloroform and bisul- 

 phide of carbon, as well as in petroleum ether. The specific 

 gravity of fine transparent fragments of aloes, dried at lOO'^C, 

 and weighed in the last-natned fluid at IG^C, has been found to 

 be 1*3G4, showing that aloes is much more ponderous than most
